Title: Plasma etching
Inventor: KOSHIO ATSUSHI
IPC: H01L21/302
Filed: 1989-08-16
Abstract: PURPOSE:To stabilize plasma state and improve working accuracy by using a parallel planer plasma etching device and carrying out the etching in two separate steps with a high frequency and a low frequency power sources when a silicon dioxide film is etched. CONSTITUTION:Opposed electrodes 2, 3 are disposed in a chamber 1. A semiconductor wafer 6 covered with a silicon dioxide film is placed on an electrode 2 in the chamber 1, wherein a mixed gas of CHF3 and CF4 is controlled to be at a predetermined pressure. In a first step of etching, a contact hole forming part of the silicon dioxide film is etched to about 90% of the film thickness by applying low frequency power between the electrodes 2, 3 from a low frequency power source 5. Then, the power source is switched to a high frequency power source 4, and high frequency power is applied between the electrodes 2, 3 to etch the remaining part of the silicon dioxide film to form the contact hole.

Title: Make-up cosmetic
Inventor: YOSHIDA MASASHI
IPC: A61K8/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a new make-up cosmetic with the improved compatibility with skin, free from offensive odor peculiar to protein by formulating a wool and or hair component into the original cosmetic. SOLUTION: Wool and/or the hair are finely ground to <=100μm particle size, and s-cyanoethylated to remove insoluble cuticles. The resultant hydrophilic s-cyanoethylated keratin powder is formulated into the original cosmetic preferably at 1-95wt.% to the whole weight of the make-up cosmetic. The scyanoethylated keratin is intrinsically safe for human bodies because it is keratin protein, and the make-up cosmetic which contains the s-cyanoethylated keratin has also high safety to the skin because the cosmetic contains no or scarce surface-active agent. In addition, this make-up cosmetic is excellent in transparency and thermal insulation.

Title: Electrophotographic film to be transferred
Inventor: TAKEHANA TADASHI
IPC: C08J7/04
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic film to be transferred which is excellent in both of a traveling property and blocking property by providing the other surface of a transparent base with a back layer consisting of a conductive primer coating layer and a friction-coefft. decreasing layer. SOLUTION: The electrophotographic film to be transferred which is formed with an image receiving layer 12 on one surface of the transparent base 11 and is formed with the back layer 13 on another surface of the transparent bas 11 is illustrated. The back layer 13 consists of the conductive primer coating layer 14 and the friction-coefft. decreasing layer 15. The conductive primer coating layer 14 is formed on the transparent base 11 and the wear-coefft. decreasing layer 15 thereon. The conductive primer coating layer 14 bears the effect of suppressing the static electricity usually generated by the transportation of the electrophotographic film to be transferred within a copying machine and the effect of controlling the charges necessary for taner transfer.  On the other hand, the friction-coefft. decreasing layer 15 acts to lower the friction coefft. of the electrophotographic films to be transferred with each other or with the transportation surface of the copying machine at the time of transportation.

Title: METHOD FOR REMOVING Ti
Inventor: WATABE KOJI
IPC: C23C16/14
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a Ti film deposited on an interlayer insulating film can be removed by increasing the flow rate of TiCl4 against that of H2 than the depositing time after changing the Ti film deposited on a silicon film to a TiSi2 film through silicification. SOLUTION: After a field oxide film 2 is formed on an Si substrate, a diffusion layer 4 is formed by injecting B into the exposed part of the substrate 1 and activating the injected B through heat treatment. Then an interlayer insulating film is deposited and a contact hole is formed on the diffusion layer. Finally, a natural oxide film formed on the diffusion layer is washed away with a dilute hydrofluoric acid and the substrate 1 is carried in an ECR-CVD device to removes Ti on the insulating film by forming a TiSi2 layer 6 on the diffusion layer. At the time of forming the TiSi2 layer, the TiCl4/H2 introducing ratio is controlled to 0.6-1.0. Then a Ti film is etched by generating plasma by increasing the TiCl4/H2 introducing ratio.

This computation is realized by an application program in a computer. Concretely, the signals 8 DELTAX1, DELTAY1, DELTAX2 and DELTAY2 at times t1 and t2 at two points being different in terms of the time are taken in, and based thereon, a slippage at a time (t), i.e. angles 18 XA and YA are determined from the equation. Based on the data on the two points inputted in this way, the angles 18 XA and YA are outputted by primary approximation. Besides, the slippage of the time is determined from a predicted angular velocity at a prescribed time and outputtede as the automatic offset time.

Filed: 1984-10-12
Abstract: PURPOSE:To eliminate overlooking of defects, by controlling the light receiving time by varying the scanning cycle of a linear array image sensor to always keep the exposure sensitivity level of the linear array sensor constant. CONSTITUTION:An input signal converted into electricity from light from a linear array image sensor 1 for sensing heat radiation and a linear array image sensor 2 for sensing reflected light of an externally illuminated light on the surface of a cast billet is fed to an LPF7 to determine the extra polation line of the signal. From this extra polation line, readings during one scan are obtained by a pulse applied from a quantity of light data sampling control circuit 12 through a quantity of light sampling 8 and the data points averaged with an averaging circuit 9 to calculate the difference from the target quantity of light with a gain setting circuit 10. The alteration value of the necessary exposure time is calculated based on the deviation. The results of the calculation are inputted into a exposure time controlling circuit 11 to control the exposure time by changing the interval of the photoelectric conversion start pulse of linear array image sensors 1 and 2 and thus, the output signal of a flaw detection camera can be outputted with a fixed signal level.

Abstract: PURPOSE:To easily obtain a magnetic card to be used for the prevention of forgery by sticking a magnetic recording medium consisting of a low magnetic resistance magnetic layer and a high magnetic resistance magnetic layer to a card material by means of a laminating tape. CONSTITUTION:The magnetic recording medium forming laminating tape 20 is constituted by successively laminating the high magnetic resistance magnetic layer 3, the low magnetic resistance magnetic layer 2 and a protection layer 13 on a base film 14. A barrier layer for preventing the mutual action of both the layers 2, 3 is preferably arranged between both the layers 2, 3. Namely the prevention of forgery is attained by disabling a card forger to erase information recorded on the layer 3 of a magnetic card and the magnetic resistance of the layer 3 is set up to three times or more that of the layer 2. Thereby user information recorded on the layer 2 can be erased by the magnetic resistance of a magnetic recording device to be normally used, but card inherent information recorded on the layer 3 is left without being erased.
